Passengers on a Qatar Airways flight going from Athens, Greece to Doha had to endure harsh heat for more than three hours after the aircraft's air conditioning system failed. The technical failure left the passengers sweating, and a few even removed their clothes due to the heat, as per reports. Garth Collins, a sports massage therapist, shared a clip of Damian Collins, a Muay Thai fighter, who was on the flight. Damian can be seen sweating severely while people behind him constantly fan and try to hydrate themselves.

Damian is a fit, conditioned athlete; imagine the stress and danger for any normal individual. Currently, the passengers are queueing at the check-in counters to find out when they will be flown out of Athens and what will be done about their connecting flights in Doha," wrote Garth as he shared Damian's clip.
